SIMON DOKK OLSEN, OF BROOKLYN, NEW YORK, ASSIGNORy TO PRIEiCISION GLASS GRINDING- MACHINE COMPANY, OF SIOUX FALLS, SOUTH DAKOTA, A CORPORATION 0F soU'rH DAKOTA.

T 0 all whom it may concern. f l I .Be it known that I, SIMON DokK OLsiiN,

a citizen of the United States,'resi ding at Brooklym, in the countyr of Kings and State of New York, have invented certain new and useful Improvements in Grindin Machines, of which the following is a speci cation, reference'being had' therein to the accompanying drawing.

YThis invention relates toa vmachine forr grinding glass and other Stoppers, but particularly glass Stoppers, in such wise that the Stoppers may be interchangeably mated chuck which, however, shown with a stopper in it a finishing wheel, of carborundum shown in elevation.

or the like, being in contact with the surface of the stopper in the clitick. also shows a rough grinding wheel, 0f cai.'- borundum or the like, `out of contact with the stopper. Fig. 2 is a front elevationx of the machine. F 3 is mainly a' lengthwise sectional view of the machine on line 3-3,. of Fig. 1, sonic of the parts, however, beingu Fig. 4; is mainly a hori-y zontal sectional view of the machine on linefl Fig. 5 is a 4 4 of Fig. 3, looking down. transverse sectional view, at line 5-5 f Fig with the rough grinder ind finishing grinder wheels in elevation. Fig. 6i's a cross-sectional view of the machine atline G-G of Fig. 3, some of the parts being shown in elevation. Fig. 7' is an end view of the machine taken from the left of Fig. 3. Fig.

8 is an end view of the machine taken from the right" of Fig. 3. Fig. 9 a view show.- ing the main driving shaft and back gear shaft with certain cams and 'gears in sectiong'lhe view being a'dcvelopnient of the.,v

parts shown. This view may he considered illustrates, particularly,' clutch mechanism' for operating certain gears and the: stopper- ChuCkng-cam, the belt-driving cam, the stopper-feeding cam, the stopper-roughening cam, the stopper-finishingcam, and at the right-hand. end, a spiralggearlfo'drw ing a rocker arm cam (not here shown) for laterally vibrating both grinders. Fig. 10

is an enlarged sectional detail, at .a line vcorresponding to line 10-10 Ofi'Fig. 7, of a clutch mechanism with which the main4 driving shaft is provided, and whereby, when clutched at the right, the cain's for actuating the rough and finishing grinders are operated through the back gear' mechanism shown in Fig. 9; and when clutched at the left, the cam for the stopper carrying mech. anism, the cam for the stopper chucking yalso as a section on liI1e9-9 of Fig. 7. `l`It.

mechanism and the cam for the belt-shaft llever are operated through the said/*back gear mechanism. Fig. 11 is an enlarged view of the clutch mechanism shown in Fig. 10 and shows clutch pinions loosely mounted on. the main driving shaft with a clutchin inoperative position between them. Fig. 12 is a cross-sectional detail of said clutch lmechanism at line 12-12 ofFig. 10, parts being shown in elevation. Fig. 13 is a crosssectional detail of the clutch mechanism at line 13-13 of Fig. 10, parts being shown in elevation. Fig. 14 is an elevational detail of automatic shifting mechanism for said' clutch.' Fig. 15 is in part an elevational and in part a sectional det-ail of a portion of said automatic shift-ing mechanism at line 15-15 of Fig. 14. Fig. 1G is a top plan view of said automatic shifting mechanism; partly in section at line 16-16 of Fig. 14, looking down'. Fig. 17 isa partial top plan view of said automatic shifting mechanism looking down, on the construction shown in Fig. 14, .and more fully` shows said shifting mechanism. Fig. 18 is a vertical central section et the stopper chuck spindle at right anglesto the plane of the section indicated line 18T-l ofFig., 3. Figs. 19, 20, and

21 are respectively cross-sectional elevations of said chuck spindle mechanism at lines` 1a1e,2o 2o, ond 21-21 of Fig. 1s. Fig.

22 is an inner endelevation of said stopper chuck meohanism-viewed from the righthand end of Fig. 18. Fig'23 is a length'- 5 lwise central section at line 23-23 of Fig. 1

of mechanism for rotating and laterally v ibrating the rough grinder. Fig. 24 is a`nele' vation mainly 'of the finishing wheel, yits casing and support, but partly lnsectionf on-a .line corresponding to line 2lb-24 of Fig.1, the section showing a bell-crank .and yoke con nectionfor sliding said support' toward and from a stopper.y F ig.v 25 is a top plan view of the finishing wheel and the' frame which supports its driving shaft, the frame being adjustable on a slidable support t-o set the finishing wheel atfdiii'e'rent angles in relation to longitudinal axis of the machine...

' This view is partly in section at a line cor.- responding to a line 25-25 of Fig. 6. Fig.

26 is a vertical sectional detail, at a line cor'- responding to line 26-26 of Fig. 1, of thev mechanism for adjusting the rod that vibrates the finishing wheel laterally during its rotation. Fig. 27 is a plan view of mechanism shown in Fig'. 26. Fig. 28 is a vertical sectional view, atline 218,-28 of Fig. f
